Jose, that is a lovely flower shot.
Leighton, I only used a filing tools. I was afraid that I can damage it with the power tool. That's why it took me almost 1hr to get it done.
Georg, thanks. Yes, that image of her on the stairs was from the 15mm. I still keep that lens.
Ray and Paul, thanks. Great shots on your last post, Paul. I like the first one the most.

Here is a quick shot from my 16mm f3.5. My daughter wanting to be Rapunzel princess.
